Terms for earphone Sound Quality Evaluation

Today, I saw one on the Internet.ArticleI think it is a good term for evaluating the sound quality of headphones. I can also learn the terms to help myself accurately express the sound quality characteristics during normal communication. I added the relevant terms in English. please correct me if not.

Audio domain:Dynamic Range)

Tone:Also known as audio products, one of the basic attributes of sound, for example, Erhu and pipa are different sounds (tone color or Timble)

Audio dyeing:Naturally, the opposite of music is neutral, that is, the sound is infected with some features that the program itself does not have. For example, the voice obtained from a speech to a jar is a typical audio dyeing. It indicates that the replay signal contains more (or less) components, which is obviously a distortion. (Harmonic)

Distortion:The output of a device cannot completely reproduce its input, resulting in waveform distortion or increase or decrease of signal composition. Dynamic: the ratio of maximum information to minimum information can be recorded.

(Distortion)

Transient Response:The ability of devices to follow sudden bursts of music. A device with a good transient response should respond immediately as soon as the signal arrives, and the signal stops suddenly and never flags. (Typical instrument: Piano) (transient)

Signal-to-noise ratio:Also known as the signal-to-noise ratio, the signal's useful components are compared with the intensity of the noise, often expressed in decibels. The higher the signal-to-noise ratio of a device, the less noise it generates. (SNR)

Air feeling:It is an acoustic term used to indicate the openness of a Tweeter or the space gap between the instrument in the sound field. In this case, the high-frequency response can be extended to 15 kHz-20 kHz. The antonyms include "dull" and "thick )". (Widen)

Low Frequency extension:The minimum replay frequency of an audio device. The system is used to determine the extent to which the audio system or speaker can dive during bass replay. For example, the low frequency of a small subwoofer speaker can reach 40Hz, while that of a large subwoofer speaker is down to 16Hz. (Bass)

Bright:It refers to the high frequency segment of 4khz-8 kHz. At this time, the harmonic wave is stronger than the fundamental wave. There is no problem with the brightness itself. The concert on the scene has a bright sound. The problem is that it is so bright that you have a good sense of detail. It is annoying to be too bright (or even scream. (Clear)
